This damselfly is very similar to the common blue damselfly, but the most obvious difference is the thorax (below the head) is more striped on the azure, whereas the common blue is more solid blue. Found all around the lake and river, often in long grass. They are mainly around May to July.

The female shown below, is a totally different colour, mainly white, with a hint of gold. Male and female having different colours is normal in damselflies. You can see the pattern of where the colours are is the same in both though.
